Abstract
A high performance follower device coupled with a slew enhancement circuit includes an amplifier circuit containing a follower device connected to a three-terminal device, whereupon current drawn through the three-terminal device is amplified through a current amplifier and sent to the source terminal of the follower device to stabilize the output voltage when the input signal is changed rapidly or if the output voltage is disturbed by a changing output load. The presence of a cascode device also allows for the bootstrapping of the follower device.
